This guide outlines the changes needed to prepare your app for iOS 14.
Prerequisites
- Google Mobile Ads SDK 7.64.0 or higher
Enable SKAdNetwork to track conversions
The Google Mobile Ads SDK supports conversion tracking using Apple's
SKAdNetwork
,
which means Google is able to attribute an app install even when IDFA is
unavailable.
To enable this functionality, you will need to update the SKAdNetworkItems
key with an additional dictionary in your
Info.plist
.
<key>SKAdNetworkItems</key> <array> <dict> <key>SKAdNetworkIdentifier</key> <string>cstr6suwn9.skadnetwork</string> </dict> </array>
Request App Tracking Transparency authorization
To display the App Tracking Transparency authorization request for accessing the
IDFA, update your Info.plist
to add the NSUserTrackingUsageDescription
key
with a custom message describing your usage. Below is an example description
text:
<key>NSUserTrackingUsageDescription</key> <string>This identifier will be used to deliver personalized ads to you.</string>
The usage description appears as part of the App Tracking Transparency dialog, as shown below:

To present the authorization request, call
requestTrackingAuthorizationWithCompletionHandler:
.
We recommend waiting for the completion callback prior to loading ads, so
that if the user grants the App Tracking Transparency permission, the
Google Mobile Ads SDK can use the IDFA in ad requests.
Swift
import AppTrackingTransparency import AdSupport ... func requestIDFA() { ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in // Tracking authorization completed. Start loading ads here. // loadAd() }) }
Objective-C
#import <AppTrackingTransparency/AppTrackingTransparency.h> #import <AdSupport/AdSupport.h> ... - (void)requestIDFA { [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) { // Tracking authorization completed. Start loading ads here. // [self loadAd]; }]; }
For more information about the possible status values, see
ATTrackingManager.AuthorizationStatus
.
Disclose data usage in the App Store
Apple requires that developers publishing apps on the App Store disclose certain information regarding their apps' data use. Apple has announced that these disclosures will be required for new apps and app updates starting December 8, 2020.
